Description

Technical Field

[0001] This utility model relates to the field of optical cable technology, specifically a novel optical cable with anti-rodent bite effect. Background Technology

[0002] Optical fiber cable is a communication cable with optical fiber as the core transmission medium and composed of a multi-layered protective structure. Its basic structure includes a fiber core (high-purity glass / plastic fiber), cladding (using the principle of total internal reflection to transmit light signals), buffer coating, tensile reinforcement (such as aramid yarn), and a flame-retardant and waterproof outer sheath. Compared with traditional cables, optical fiber cable has significant advantages such as large transmission bandwidth (up to TB level), low loss (relay distance of over 100 kilometers), resistance to electromagnetic interference, and strong confidentiality. It has become a core infrastructure of modern information society. According to the transmission mode, it can be divided into single-mode (long-distance backbone network) and multi-mode (short-distance local area network). It is widely used in 5G communication, Internet, broadcasting transmission, defense communication, smart grid and other fields. The manufacturing process involves key technologies such as optical fiber drawing, precision cabling, and material modification. It continues to develop towards ultra-low loss, large core count and miniaturization, supporting the massive data transmission needs in the global digitalization process.

[0003] In existing technologies, optical cables are buried in the soil before use for communication. However, because there are no protective structures on the existing optical cables, they can be chewed by rats, leading to damage and rendering them unusable.

[0004] Therefore, a new type of optical cable with rodent-proof properties is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a novel optical cable with anti-rat bite effect to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a novel optical cable with anti-rat bite effect, comprising an inner protective layer, a flexible layer bonded to the outer surface of the inner protective layer, a first rodent repellent layer bonded to the outer surface of the flexible layer, a second rodent repellent layer bonded to the outer surface of the first rodent repellent layer, and an outer protective layer bonded to the outer surface of the second rodent repellent layer.

[0007] Preferably, the flexible layer is made of Kevlar braided mesh.

[0008] Preferably, the first rodent-repellent layer includes two low-smoke halogen-free sheaths. One low-smoke halogen-free sheath is mounted on the outer surface of the flexible layer on one side of its inner surface, and the outer surface of the other low-smoke halogen-free sheath is bonded to the inner surface of the second rodent-repellent layer. Fine glass shards are filled between the two low-smoke halogen-free sheaths.

[0009] Preferably, the second rodent-repellent layer is filled with microcapsules.

[0010] Preferably, the thickness of the flexible layer is between 1.0 and 1.5 mm, the thickness of the second rodent-repellent layer is between 0.1 and 0.5 mm, and the thickness of the outer protective layer is between 0.5 and 1.0 mm.

[0011] Preferably, the thickness of the flexible layer is 1.2 mm, the thickness of the second rodent-repellent layer is 0.3 mm, and the thickness of the outer protective layer is 0.8 mm.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention, through the design of an outer protective layer, a first rodent-repellent layer, a second rodent-repellent layer, and a flexible layer, utilizes the nylon material on the outer protective layer to effectively increase the toughness of the optical cable when the inner protective layer is pre-buried in the soil. Simultaneously, the thorn structure on the outer protective layer causes mechanical stinging when rodents or rats come into contact with it. The microcapsules in the first rodent-repellent layer release menthol and capsaicin when a mouse or rodent bites onto the second rodent-repellent layer, creating a dual sensory attack on the mouse through taste and smell. The second rodent-repellent layer facilitates the biting of small glass shards, causing stinging in the mouse's mouth and effectively deterring it. Finally, the flexible layer, with its excellent flexibility, increases its adaptability during use. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example: Please refer to Figure 1-2 This utility model provides a technical solution: a novel optical cable with anti-rat bite effect, comprising an inner protective layer 1, characterized in that: a flexible layer 2 is adhered to the outer surface of the inner protective layer 1, a first rodent-repellent layer 3 is adhered to the outer surface of the flexible layer 2, a second rodent-repellent layer 4 is adhered to the outer surface of the first rodent-repellent layer 3, and an outer protective layer 5 is adhered to the outer surface of the second rodent-repellent layer 4. The outer protective layer 5 is made of nylon material, and its surface is formed by pressing to form a micron-level imitation porcupine thorn array. The height of the imitation porcupine thorns is 200μm, and the tip curvature radius is 5nm. The surface of the porcupine quills is coated with superhydrophobic fluorosilane with a contact angle >160°. Its functions are: the quill structure causes mechanical stinging when rodents come into contact with it; hydrophobic and antifouling: reducing odor residue and avoiding attracting rodents; the thickness of the outer protective layer 5 is between 0.5-1.0 mm, preferably 0.8 mm; the height of the porcupine-like quills in the outer protective layer 5 is 200 μm, covering the base surface of the outer protective layer 5; the quill spacing is 300 μm, and they are densely distributed in a hexagonal pattern; hydrophobic coating: 5 μm superhydrophobic fluorosilane vapor deposition layer.

[0019] Furthermore, the flexible layer 2 is woven from Kevlar mesh, and the thickness of the flexible layer 2 ranges from 1.0 to 1.5 mm, with the preferred thickness being 1.2 mm. The Kevlar mesh 21 uses 0.4 mm 200Tex fiber, is cross-woven at 45°, and has a surface density of 120 g / m². Compared to metal weaving, which is heavier and not conducive to outdoor installation, and is susceptible to rust and corrosion due to outdoor environmental factors, Kevlar weaving is lightweight, easy to install, and less prone to rusting in the field.

[0020] Furthermore, the first rodent-repellent layer 3 includes two low-smoke halogen-free sheaths 31. One low-smoke halogen-free sheath 31 is mounted on the outer surface of the flexible layer 2 on one side of its inner surface, and the other low-smoke halogen-free sheath 31 is bonded to the inner surface of the second rodent-repellent layer 4 on its outer surface. Fine glass shards 32 are filled between the two low-smoke halogen-free sheaths 31. By filling the space between the fine glass shards 32, when rodents or rats bite onto the first rodent-repellent layer 3, the sharp points of the fine glass shards 32 can effectively cause stinging pain to the mouths of rodents or rats, thereby effectively repelling them.

[0021] Furthermore, the second rodent-repellent layer 4 is filled with microcapsules, and its thickness ranges from 0.1 to 0.5 mm, preferably 0.3 mm. When rodents bite and generate pressure >5 kPa, the pressure compresses the microcapsules, causing them to rupture and release the repellent. The chemical synergy—menthol's olfactory repellency and capsaicin's pain stimulation—creates a dual sensory attack, achieving a repellency efficiency >98%. The microcapsules are formed by alternating double-layer deposition, with each layer being 100 μm thick and containing microcapsules with a diameter of 10 μm, and a density of 102.4 The fiber optic cable is equipped with a per mm² unit, which can further drive away rats or rodents and prevent them from damaging the fiber optic cable.

[0022] This utility model is not limited to the above-described embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of this utility model shall be considered equivalent substitutions and shall be included within the protection scope of this utility model.
